The Arduino is an open-source computer hardware/software platform for building digital devices and interactive objects that can sense and control the physical world around them.

For many years now, people have been improving their tools, studying the forces of nature, and bringing them under control, using the energy of nature to operate their machines. The last century is noted for the creation of machines that can operate other machines. Nowadays the creation of devices that interact with the physical world is available to anyone.

One such creation is the Arduino. Using simple integrated circuit boards, users can build high-end IoT projects like smart homes, robotic arms, drones, and the likes in a matter a few hours.

Arduino is a prototype platform (open-source) based on easy-to-use hardware and software. It consists of a circuit board, which can be programed (referred to as a microcontroller) and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to the physical board.

The key features are −

• Arduino boards can read analog or digital input signals from different sensors and turn it into an output such as activating a motor, turning LED on/off, connect to the cloud, and many other actions.

• You can control your board functions by sending a set of instructions to the microcontroller on the board via Arduino IDE (referred to as uploading software).

• Unlike most previous programmable circuit boards, Arduino does not need an extra piece of hardware (called a programmer) to load new code onto the board. You can simply use a USB cable.

• Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program.

• Finally, Arduino provides a standard form factor that breaks the functions of the micro-controller into a more accessible package.

Features of the Arduino UNO:

• Microcontroller: ATmega328.
• Operating Voltage: 5V.
• Input Voltage (recommended): 7-12V.
• Input Voltage (limits): 6-20V.
• Digital I/O Pins: 14 (of which 6 provide PWM output)
• Analog Input Pins: 6.
• DC Current per I/O Pin: 40 mA.
• DC Current for 3.3V Pin: 50 mA.

2. Building Arduino robots and devices

Our course consists of a series of practical problems on making things that work independently: they make their own decisions, act, move, communicate with each other and people around, and control other devices.

Course rating: 4.3 out of 5.0 ( 95 Ratings total)

In this course, you will :

• Demonstrate how to assemble such devices and program them using the Arduino platform as a basis.
• After this course, you will be able to create devices that read the data about the external world with a variety of sensors, receive and forward this data to a PC, the Internet, and mobile devices, and control indexing and the movement.
• The creation of such devices will involve design, the study of their components, the assemblage of circuit boards, coding, and diagnostics.
• Along with the creation of the devices themselves, you will perform visualization on a PC, create a web page that will demonstrate one of your devices, and figure out how an FDM 3D-printer is configured and how it functions.
• Besides those keen on robotics or looking to broaden their horizons and develop their skills, the course will also be useful to anyone facing the task of home and industrial automation, as well as to anyone engaged in industrial design, advertising, and art.
• The entire course is dedicated to practicing, so the best way for you would be to get hold of some electronics, follow the illustrated examples, and experiment on your own.
